I had a hiccup lately, try this once ingame mode, on the keyboard, hit Alt/Ctrl/delete, like 10 times, then keep pressing on the "windows" btn. that did it for me, and it went to the next turn about 3 minutes of doing this back and forth, sometimes, it works, sometimes it doesnt . . otherwise its up to TB. . .
Wouldn't it simply go to taskmanager though?
